Wearable electronics: A look into the future

What might the future of wearable electronics look like? We asked the experts what to expect:

By 2014: Apple's iWatch is likely, as are more sophisticated sensors that collect personal and physical data to help us improve our lives by correlating data. For example, skin temperature and sleep movement could be monitored together to more accurately track caloric burn.

By 2020: Sensor sophistication and processing speed will continue to evolve. We'll see a more natural integration among all of our various computing devices, which will become smaller and lighter over time. Glasses and visors, for example, will feature displays built into the lenses, allowing completely hands-free texting and essentially creating a sort of virtual telepathy.

By 2050: We might have sensors implanted in our bodies that will collect extensive real-time data about our health, giving us feedback right after we eat a meal about what's happening in our digestive system. We'll start modifying ourselves with implants and upgraded organs, so, for instance, Google Glass might not be something you wear but rather a feature inside an eyeball replacement.
